CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 376,100, dated January 10, 1888.

Application tiled October 21, 1887. Serial No. 252,951. (No model.) v

. fective, and no brake has as yet been putin use on such cars which is eective and practical, particularly'on an incline. My improved brake will stop the car on any incline and at any speed. The brakes now in use are also complicated and expensive.

In the accompanying drawings, forming part of this specification, Figure 1 is a side View of a platform railway-car with my improved brake attached. Fig. 2 is a bottom View OI the car with my brake attached. Figs. 3 and 4 are views of the inclined surfaces I employ to bring the brake-shoes on and off the carwheels. When the brake is not in use, the inclined surfaces appear as shown in Fig. 3, and when in use and applied these surfaces appear as shown in Fig. 4; and Fig. 5 is a View of the brake-shoe.

A represents the platform of the car, B the axles, and C the wheels. Opposite each wheel are preferably placed the posts a, which are attached to the platform of the car in any suitable manner. Attached in any convenient manner to these posts a are the blocks a', having the inclined surfaces or faces c2. In

the drawings these posts a are kshown used in connection with the brake which operates against all the wheels. In connection with the short brake, which operates only against either the two front or rear wheels of each truck, I use the posts a3. also each provided with a block, as a', having an inclined surface, a2, similar to the posts a.

A/ represents the long frame-work which carries brakes for each wheel, and A2 the short frame-work carrying brakes for a lesser number of wheels. These frame-works A and A2 These posts c3 are have each two long bars, b, connected at each end in any preferable manner-in my case by the cross-bars b. tach, in any preferable manner, to the bars b the bars b2. To the ends of these bars b2, I attach the brake-shoes D, preferably by screwandnut'connection d. To keep the brakeshoes D in proper position and properly adiusted, I usually connect them by the rod` d. Atsuitable points on the bars b, I locate, in any suitable manner, the blocks e, having the inclined faces e. These blocks e are so located on said bars b that they will coact with the inclined faces on the blocks c on the posts a and a3 at the proper time to bring the brakeshoe away fromor on the wheels.

The brake frame-work is suitably attached to the brake-spindle E by the rod-andchain connection F. The posts are not only useful to support the blocks a', but also to act as guides for the bars b. I may, when desired, provide additional guides. G represents a spring attached to one of the bars b2 of each ofthe frame-works A and A, as shown in Fig. 2. This spring assists in throwing the brakes olf' the wheels.

At any desired poi/nts I atn 75 'lhe brake shoes D are preferably of the peculiar wedge-shape construction shown in Fig. 5; but they may be of any other suitable shape. Usually the ends or tips 7L of these shoes D are made of steel, and the rest ofthe shoe is cast. Vhen not in use, the brake-shoes D are up and away from the wheels, and the inclined blocks e rest on the blocks c', as shown in Fig. 3, VW'hen it is desired to apply the brake, the frame-work A or A2, through the agency of any desired mechanism, is moved forward or backward, according to the direction in which the train or car is moving, and the inclined faces e on the blocks e ride over the inclined faces a2 of blocks c', (see Fig. 4,) thus bringing the brake-shoes D on the wheels and stopping the car. Vhen the brake is released, the blocks e ride back on the blocks a', the spring G assisting.

The brake-shoes D are the main feature of myinvention, and when applied to the wheels the car must stop, as they wedge in between the wheel and the track. They can be used in connection with any othei` form ofhmke 2. In a ear-brake frame-work A, parts A mechanism, and one or more of them may be and A2, posts a :1nd a3, blocks a and e, havlng used, as desired. inclined faces f and e', spring G, and bars b'l, Whab I claim as new and of my invention, having rigidly attached to them the brake-shoes 5 and desire to secure by Letters Patent, is- D, substantially as sei; forth.
